The next-generation medicals can be tiny nano-drills.

Molecular robots are tools that can use for many purposes. Molecular nano-drill can destroy bacteria mechanically. When nano-machines are used for medical treatment. The system can remove those systems from the body quite easily. There are two ways how to make that thing. 

The first way is by connecting some magnetic metal to those molecules. Then the magnetic field can use to pull those molecular machines out from the body. Another way is to use special enzymes that are destroying the molecule. The problem is that the nano-drill bases benzene molecules and those molecules cause cancer. 

And that makes it the next-generation antibiotics. The problem with antibiotics is that it turns immune against antibiotics. But there is no way, how the bacteria can resist nano-machines. 

Nano-drills can do many more things than acting just like a bacteria killer. They can remove the waste from the body. And in some visions, those nano-drills can remove plaque from the synapsis. And that thing can be the next-generation treatment for Alzheimer's. 

The nano-drills can also remove things from the blood vessels. And that thing can open closed blood veins in the case of an infarct. The benefit of those nano-drills is that they can go to places where regular scalpels cannot operate. They can also remove single cancer cells from the body. 

The molecular nano-drills can use also for drilling holes in the cancer cells' protein membrane. The aiming of those molecular machines to the right cells will happen by connecting certain enzymes or nutrients to those molecules. And then the own immune system will transport the nano drill to the right cells. 

The problem with nano-drills is how they can aim at the right cells and how to deny them to destroy other cells. If there is some special nutrient that the targeted cells are using the nano drill can benefit that thing. The nutrient can involve enzymes that are making the protein-membrane weaker. Then the nano-drills can use feely because the cells must be prepared so that the nano-drills can make the hole in the membrane.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
